Bulugh al-Maram 13 Oaths and Vows كتاب الأيمان والنذور 3

وَعَنْ أَبِي هُرَيْرَةَ – رضى الله عنه – قَالَ: قَالَ رَسُولُ اَللَّهِ – صلى الله عليه وسلم -{ ” يَمِينُكَ عَلَى مَا يُصَدِّقُكَ بِهِ صَاحِبُكَ” } وَفِي رِوَايَةٍ: { “اَلْيَمِينُ عَلَى نِيَّةِ اَلْمُسْتَحْلِفِ” } أَخْرَجَهُمَا مُسْلِمٌ 1 . 1 – صحيح رواه مسلم ( 1653 ).

Narrated Abu Hurairah (RA): Allah’s Messenger (صلى الله عليه وسلم) said: “Your oath will be about that matter which your adversary has required you to swear about so that he will believe you.” In another narration: “An oath is to be interpreted according to the intention of the one who requested it (Al-Mustahlif).” [Muslim reported both narrations].
